Filed: 1968-05-21
Abstract: 1,212,036. Charging glass lehrs. U. G. TABLEWARE Ltd. 16 May, 1969 [21 May, 1968], No. 24191/68. Heading F4B. [Also in Division B8] A device for transferring glassware (not shown) from a conveyer to a lehr comprises a normally horizontally disposed pivotally mounted frame 12, carrying a fluid pressure cylinder 10, the piston-rod 20 of which carries a transfer bar 22, the piston-rod 20 being actuated to move outwardly of the cylinder, means 26 adapted to pivot the frame 12 in a vertical plane upon the piston-rod 20 reaching the limit of its outward movement, means adapted to retract said piston-rod 20 during such pivoting, means adapted to return said frame 12 to its normal position upon retraction of the piston-rod 20, and means delaying the retraction of the pistonrod so that the retraction does not take place immediately the piston-rod reaches the limit of its outward movement. Due to this delay the bar 22 thus has a steadying effect on the articles transferred to the lehr. The sequence of operations is controlled by a system of pneumatic valves (Fig. 3, not shown) which is initiated for each transfer operation by a solenoid-operated valve (52). The delay is provided by a pneumatic delay valve 32. The valve 52 is energized by the operation of a switch 48 (Fig. 2), each time a member 46 on an endless chain 44 engages a member 50 of the switch. The chain 44 is indexed in synchronism with the conveyer.

Abstract: 384,621. Type-bar-making machines. HART, H., 9, Kingsway, London.-(Mergenthaler Linotype Co. ; 29, Ryerson Street, Brooklyn, New York, U.S.A.) Aug. 30, 1932, No. 24207. [Class 100 (iii).] Matrices.-Relates to the formation of thick matrices with relatively long distributing-teeth, in order to give good support and to avoid tilting. The web c<3>, in which the V-shaped notch is formed, is made to extend from one side of the matrix at least to the plane containing the centre of gravity, and a vertical recess c<5> is formed by drilling downwards through the base of the U-shaped recess c<2>, that is formed adjacent to the notch. In order to diminish the difficulty of forming the lowest pair of teeth, a hole c<6> is drilled transversely through the matrix, and opens at one end into the recess c<5>, so that, in the subsequent formation of the teeth, only a very small amount of metal has to be removed in forming the lowest pair of teeth, and the strain imposed on the tool is reduced. In order to reduce the weight of the matrix, two superposed recesses c<10>, c<11> are drilled transversely in the body. The upper recess c<10> communicates at its inner end with the vertical recess c<5>, and includes a part of the transverse hole c<6>.

Abstract: 814,291. Controlling aircraft. FAIREY AVIATION CO. Ltd. Aug. 21, 1956 [Aug. 23, 1955], No. 24281/55. Class 4. In an aircraft having servo operated control surfaces, mechanism for providing a sense of " feel " when the control column 12 is moved to operate the valve 13 of a servomotor 14 comprises an arm 15, pivoted to a control rod 11, and pivoted co-axially with a cam arm 16 to which it is connected through a hydraulic clutch 17. The end of the arm 16 is formed with a cam slot 18 which co-operates with a roller 19 carried by one end of an arcuate blade spring 21 of part-circular form and securely mounted at 22. Movement of the arm 16 in either direction causes roller 19 to move up one or the other of the cam faces thereby bending the spring inwards and introducing a force opposing the movement of the control column. To vary the rate of the spring 21 a fulcrum arm 23 is mounted to turn about the same axis as arm 16 and it carries at its end a roller 24 engaging the inner periphery of spring 21. The arm 23 is operated by a rack and pinion mechanism operated by a small fluid-pressure servo mechanism controlled automatically by an instrument responsive to Mach number and indicated airspeed. The valve controlling the lastmentioned fluid pressure servo mechanism may be connected through an electrically operated fail-safe valve controlled by a button on the control column 12 whereby the arm 23 and roller 24 are moved to a position in which spring 21 has a maximum effective length to provide minimum opposition to movement of the control column.

Abstract: 1,242,053. Moulding surgical appliances. BAKELITE XYLONITE Ltd. 27 May, 1968 [25 May, 1967 (2)], Nos. 24457/67 and 24473/67. Heading B5A. [Also in Divisions A5, B8 and C3] Articles are formed from a sheet of a rigid or semi-rigid expanded cross-linked olefin polymer having a low thermal conductivity and heat storage capacity by (i) heating the sheet to a temperature which plasticizes the sheet so that it becomes pliable without destruction of its cellular nature, (ii) placing the heated sheet in direct contact with a body and shaping the heated sheet to the configuration of the body, and (iii) allowing the heated and shaped sheet to cool so that it sets in the configuration of the body. The sheet may be formed of low density polyethylene which has been partially cross-linked by ionizing radiation or treatment with an organic peroxide and is nitrogen-filled, e.g. the material commercially available under the Registered Trade Mark "Plastazote". The polymer may optionally be reinforced, e.g. with a sheet or strips of a higher density thermoplastics material, preferably a similar polymer to the expanded material. Other suitable expanded materials are those derived from copolymers of ethylene with vinyl acetate or ethyl acrylate, and from polypropylene. A preferred class of articles that can be formed comprises surgical articles such as orthopaedic supports, cervical collars, spinal supports, surgical footwear, splints and external prostheses; another useful class of articles comprises wrappings, casings and packages.

Title: Speech encoding and decoding
Inventor: PATTERSON THOMAS
IPC: G10L25/00
Filed: 1969-05-14
Abstract: 1282641 Speech encoding T PATTERSON 14 May 1970 [14 May 1969] 24525/69 Headings H4R and R22X In a device for encoding an electrical waveform e.g. a speech waveform, time intervals between successive occurrences of predetermined amplitudes are measured and non-linear digital outputs indicative of the length of said time intervals are then determined. A speech signal which may have been squared off in a clipper circuit together with the output from a clock 621 is incident on the first stage 601 of a dual shift register 600. The reverse unit 611 always indicates the opposite of 601. The length of the pulses are measured in the following manner. When a 1 reaches unit 610 in the shift register 600 and units 633, 632 &c. are triggered, starting at 633 to pass all the consecutive 1 units from shift register 600 to shift register 656 by means of the AND gates 624 to 633, in such a way that a non-linear companding characteristic is attained. Thus if the bottom four units 607 to 610 of shift register 600 register "1"s only the bottom three units of shift register 656 register "1"s. The stored values on shift register 656 are then fed back via the parallel output of shift register 656 to shift register 600, so that now only the end three units 608 to 610 carry "1"s. The same procedure is repeated for the left hand side of the apparatus to encode the "0"s on the units 611 to 620 of shift register 600. The values in shift register 600 are read out in sequence to control the subsequent switching of the circuit. Under the action of logic units shift registers 656 and 670, are read out in turn via an adder unit 667 to provide a series of equi-weighted pulses representing the input signal. A de-coder unit, Fig. 2, receives the input chain of pulses from a dual shift register 111. These pulses are then fed via units 140 to 149 to a shift register comprising bi-stables 160 to 169. These feed in parallel a digital to analogue converter 117 which produces a voltage output whose value is proportional to the duration of the original encoded pulses. This voltage is fed to a unit 118 which inverts a high voltage into a low voltage and vice versa so that the voltage is now proportional to frequency. The frequency proportional voltage is then used to control the bandpass characteristic of a filter 181. The left hand half of the apparatus operates in a similar manner. The two signals control filter 181 in turn. The output of shift register 111 is then pulsed out by the clock 112 and through the filter, to produce a representation in analogue form of the input. In another embodiment the variable frequency filter 181 is replaced by a series of separate filters. The value of the duration of the signal as indicated on shift register 160 to 169 is then used to control the switches so that only one filter is connected at a time. The contents of shift register 111 is then fed through the filter unit in serial form.

Title: Production of ketones and secondary alkanols
Inventor: COOPER LESLIE ERNEST
Filed: 1961-07-08
Abstract: A saturated aliphatic-ketone and a secondary alcohol are produced when the vapour of an unsaturated ketone and hydrogen react in the presence of a supported copper/nickel catalyst in the temperature 130-300 DEG C. Alternatively the reaction may be carried out in the presence of a supported copper catalyst followed by reaction of the product with more hydrogen in the presence of the copper/nickel catalyst both steps being carried out in the above temperature range. The supported copper and copper/nickel catalysts may contain 25-90% catalyst based on the total weight of catalyst and support the proportion of copper to nickel in the copper nickel catalyst being preferably 5:1 to 20:1.  The reaction may take place at atmospheric pressure or above. Higher pressures and lower temperatures tend to give increased alkanol production. By this method mesityl oxide may be converted to methyl isobutyl ketone and methyl isobutyl carbinol, and ethylidene acetone may be converted to methyl propyl ketone and methyl propyl carbinol.

Abstract: 662,126. Extruding. ETABLISSEMENTS MORANE JEUNE. Sept. 27, 1949 [March 16, 1949], No. 24808/49. Class 83 (iv). In apparatus for the extrusion of metal, e.g. lead or lead alloys, during withdrawal of the ram, molten metal is run into the container through a channel in the ram, a valve in the channel being positively controlled. As applied to sheathing a cable the container a has the temperature automatically regulated by electric heating elements c and water cooling jacket d. The cable i passes through a die g which is fed with metal from a cavity f in a block e attached to the container. A ram 1 connected to a hydraulically-operated crosshead 1a has a central bore 1b within which is inserted a metal tube 2 having cells on its outer face containing electric heating elements 3. A second tube 2a and heat insulating material 9 surrounds the tube 2. A triangular section sliding rod 5 is disposed in the tube 2 and a conical valve 4 on the end of the rod engages a seating 4a on the ram. The upper end of the rod engages a seating 4a on the ram. The upper end of the rod is connected by a cross-member 4b to double-acting hydraulic jacks 6. The channels 8 formed in the ram communicate through thermally-insulated tubes 8a and a circular feeder 8b with a lead reservoir. A chamber 10 contains reducing gas, e.g. a mixture of carbon monoxide and carbon dioxide, to prevent oxidation of any metal adhering to the walls of the container. In operation the valve is opened when the ram reaches the end of its downstroke and as the ram moves upwardly the molten lead flows into the container through the channels 8 and fuses with the residue of the previous charge. The charge is allowed to solidify in the container. The valve 4 is closed at the end of the ram's upstroke and the extruding operation is contmued when the charge is at a temperature of about 2000‹ C.

Title: Process for the separation of oxygenated aliphatic compounds from mixtures thereof with hydrocarbons
IPC: C07C29/74
Filed: 1953-09-09
Abstract: Oxygen-containing aliphatic compounds, particularly alcohols, aldehydes, ketones, esters and acids, are separated from mixtures with hydrocarbons by contacting the mixture with either aqueous methanol or ethanol in at least 3 extraction stages, the ratio by volume of the mixture to the solvent in each stage being about 1 : 1 and the water content of the solvent in the stages descreasing according to the alcohol used: for methanol, 40-60 per cent, 10 to 20 per cent and less than 10 per cent; and for ethanol, 40-70 per cent, 10 to 30 per cent and less than 20 per cent.  The mixture is preferably that obtained by the hydrogenation of carbon monoxide using a precipitated iron catalyst containing copper, CaO, kieselguhr and an alkali, such mixture containing about 55 per cent of oxygenated compounds.  In Example 1 such a mixture was first intermittently saponified at 145 DEG  C. and the product separated and the non-aqueous phase containing hydrocarbons and chiefly alcohols was extracted with 50 per cent methanol at room temperature. After separation, the raffinate phase was extracted again with 89 per cent methanol and a second raffinate obtained which was further extracted with 92 per cent methanol.  The raffinate consisted chiefly of low-boiling hydrocarbons and the extract consisted chiefly of alcohols having up to 14 carbon atoms, also small quantities of aldehydes, ketones, esters and acids.  In Example 2 a similar mixture was similarly processed but the saponification step was omitted.
